, To @125 whom it may concern.-

Be it known that 1, CHARLES C. CLARK, a citizen of the United States of iL-nerica, residing at Corning, in the county of Steuben and State of New York, have invented new and useful improvements in Motors or Engines, of which the following is a speciiicatron.

This invention relates to ecomhined air and electric motor or locomotive, the object of the invention being to provide a corn; pressed-aindriven engine in which. provision by electric means when the air-supply is d'nnnished or exhausted and for driving the e is by the united power of these agents high power is required, as when the engine is ascending heavy grades or" haniing vy loads.

Another object is to provide storing air under pressure and generating and storing electric energy when the engine is descending grades, so that the additional power thereby obtained may be utilized to increase the hauling-power and rsngeioi travel of the engine,

, With the above and other objects view the invention. consists of novel construe-- tion and combination of parts hereinafter described and claimed, reiercnce'being had to the accompanying drawings, in which- Figure 1 is a vertical longitudin invention, Fig. 2 is a rear elevetio. of the locomotive. ig. 3 is :1 irons tional view oi the tender. Fig. 42 i P section of the air-compressor, and lg. a horizontal section through the'same on line 5 5 of Fig. 4.

Referring now more particularly the drawings, the letter A designates the engine or locomotive, and Bits tender.

The tender B is provided with-e storagechamber 1 for air under pressure and a com-- muhicating inlet-nozzle or attachment 2, by which said chamber may be supplied with air from a suitable compressor t s IOljilld house or station. Communicating with the chamber 1 is asupply-pipe connected by the usual hose-coupling i with ing to an air-stozsge chamber 6 in the en ine orlocomotive. From .23 (i leads an o tlet-pipe 7, controls; 7 J v throttle-valve 8, adapted to be operated, through aconnecting-rod 9, by a throttlemeans "for lever 10, disposed in the cab of the engine. The pipe 7 conveys air from the chest or chamber 6 to the valve-chest 11 of the aircylinder 12, there being one such pipe, chest,

and cylinder and their cooperating parts on each side of the engine. The driving mechanism may be of the ordinary construction employed in steam-locomotives, and, as herein shown, consists of a piston 13, disposed within. the cylinder and provided with rod is, connected with the cross-head 15, movable in guides 16, said cross-head being attached to the usual connecting-rod 17, attached to the driving-wheels 18 of the engine.

The supp y and exhaust of air to and i'romyo have not deemed it necessary to show, as

these parts may be of any known construction. The air feeds from the storage-reservcir 1 on the tender to the storage-chamber 6 in the locomotive through. the pipes 3 and G and hose connection 4, and thence through the pipes 7 to the cylinders, the supply of air to the cylinders losing governed by the throttle-valve S to regulate the speed and power in the ordinary manner. The valves '3 and 5 are provided with valves 3 and 5, 8

respectively, which may be closed to prevent the escape of air from the reservoir 1 and chamber 6 when the locomotive is uncoupled from the tender.

The locomotive is provided with a compart-merit 21 for the reception of a storage cattery 22, which may he in iallv charged at c roundhouse or station. 1- conductors 23 and 24 from the opposite p is this battery connect with a motor 25, the armature-shafts of which are in gear with the axles of thi drivingwheels i8. The conductor 23 extends into the cab of the locomotive and has arranged therein a controller '26, by which the flow of the current to the motor may be too controlled. The electric driving means may be employed when the sinsnpply is diminished or exhausted or when it is desired to obtern high power for hauling heavy loads or pneumatic driving means and the elecl driving means may be employed for ling the locomotive.

In order to increase the power and range of travel of the locomotive, I provide means for 1 1o ascending heavy grades, in which event both 10 5 v rent to keep. the battery 22 charged may bea supply-pipe 31 communicating with the air-chamber 6 and provided with a controlling-valve 32. Each mot r-casing is proof the spent air. Upon ope ing the valves 32 air will be admitted to the iiiotoncasing to drive the motor-wheels, and thereby drive the dynamos to generate a current which will pass to the battery 22 through th conductors 28. The battery-22 may in this nanner be kept charged during the running of the 10- comotive. 'In order to compensate forthe loss of air employed to drive the dynamics,

under pressure to operate the wheel through.

' vided with an outlet-pipe 3 for the exhaustmeans are provided for supplying air to the reservoir 1 when the locomotive is traveling downgrades; These means consist of a compre ssor 34, mounted on the tender B, said compressor having a pair of superposed compressor-cylinders 35, in which operate pistons 36, connected with a common piston-rod 37, driven by an eccentric 38 from one of the axles oi the tender.

In order to maintain the compressor cool, each cylinder 35 is provided with a surrounding water-jacket 39, the two jackets being connected by a pipe 40 to permit of the free passage OftllG cooling-water from one to the other. The ackets of the upper and lower cylinders are respectively connected by sup- )ly and return pipes 41 and 42 with a chamer or compartment 43 upon the tender adaptedto contain the supply of cool water j which circulates therefrom and through the jackets back to, said storage-ch amber through the pipes just described. In practice a suitable clutch connection willobe employed for throwing the air-compressor into and out of operation, so that said compressor may be driven when the engine is descending grades the operation of the dynamos without reduction of alt-pressure. In tlns manner an amount of air sufliclent for generating a cursupplied, so as to avoid the necessity of.utilizing the air-pressure reserved for'driving the engine through its ordinary pneumaticallyoperated driving mechanism. The air taken in by the compressor is discharged therefrom through pipes 44 into the-storage-reservoir 1. If desired, the engine may be provided with i to force air into the air-reservoir 1 to permit of an electric headlight 4.,5, supplied with current by conductors 46 from the battery 22 and with a whistle 51 7, supplied with air from the chamberfi. v Y

, It will of course be understoodthat the compressor may be operated when the engine is descending grades to maintain a desired pressure in the storage-reservoir 1 in order to increase the range-of travel of the engine.

The tender may be provided with a chamber or compartment 48 to contain an auxiliary storage battery 22, which may be substituted for the battery 22 when the latter becomes inoperative from any cause. When maximum power is-required, the auxiliary battery 22 may also be arranged in circuit through suitable connections with the motor to supply current-*thereto. storage batterymay also be substituted for the battery 22 when the latter is exhausted andit becomes impossible to recharge it by reason ofinjury to the turbine-motors.

The engine and its tender are preferably constructed, as shown, to simulate the appearance ofthe ordinary steam-locomotive and its tender; but they may be of any deoperating elements Iiiay become wholly upon. the locomotive or upon a motor-car, the tender thus being dispensed with. .By pro viding the electrical driving means and the means for e l'nishing the storage-reservoir with air the power and range of travel of the engine are increased. v

v It will be seen that the construction of the driving mechanism is simple and that engines paratively low cost.
